How many employees do you have. if its more than 10 than you need to follow certain procedures otherwise not. Yu can run it as Sole proprietary Firm where there is no difference between company and the owner.If you want to go for Private limited minimum 2 partners are required and you have to follow few legal formalities. When I was looking for that in New Delhi there is few law firms who can do all formalities of incorporation in just Rs. 19000/- (Price may vary).
